. FASTENING DEVICE.

Application led .Tune 8, 1916, Serial No. 102,469.

To all whom t may concern.'

Be it known that I, MARTIN MoDoNALD, a citizen of the United States, residing at Vashington, District of Columbia, have invented new and useful lmprovements in Fastening Devices, of which the following is a specification. Y

This invention is a fastening device and includes a socket member adapted to be embedded in one of the partsto be connected, and a shank member to carry the other part and adapted to be conveniently assembled with the socket member and held rigidly therein against endwise and rotative movements.

Important objects of thepresent invention are to facilitate the assemblage of the socket and shank members; to eifectually prevent looseness of the shank member in the socketmember; to provide for tightening the device; and to provide for the convenient disengagement and separation of the parts whenever necessary.

A further object of the invention Yis to have the interconnecting portions of the shank and socket entirely housed within the latter in such a manner as to prevent the same from .workingloose under the use of the device.

With these and other objects in view, the present invention consists in the combination and arrangement of parts, as will be hereinafter more fully described, shown in the accompanying drawings, and particularly pointed out in the appended claims, it being understood that changes in the form, proportion, size and minor details may be made, within the scope ofthe claims, without departing from the spirit or sacrificing any of the advantages of the invention.

Like characters of reference indicate corresponding parts in' each of the figures of the drawings. I

Referring at first more particularly to Figs. 1 to j5, inclusive, it will be seen that the present invention includes a socket member A and a shank member B. The socket member A may be of any desired conguration and is shown in the accompanying drawings as cylindrical in shape and provided` with a non-circular bore l extending throughout the length of the socket member and open at opposite ends. Asshown in the accompanying drawings, this bore is rectangular in shape, and opposite walls of the bore are provided with ratchet teeth 2. Each set of ratchet teeth is intersected by a groove or channel 3 extending longitudinally of the socket and opening through one end thereof, for a purpose as will be hereinafter described. One end of thesocket member is provided with a head or flange 5, and extending longitudinally of the exterior of the,` socket are ribs -or wings 6 intended to prevent rotation of the socket, as will be hereinafter described. Y

The shank B is of a suitable length and is of a size and shape to fit within the bore 1 of the socket. -One end of the shank is provided with a head 7 and in the other end portion of the `shankthere is a longitudinal slot 8, extending entirely through the shank, and in this shank there is a dog or pawl 9. This dog or pawl is formed of a single piece of metal bent into U shape and straddles a pin l0 extending through the slotted portion of theshank. lEach end 11 of the dog is bent back to form a spring finger of the socket.

In the application of the device, vas shown in Figs. 1, 2 and 3, it will be seen that the part 12, say for insta-nce the body portion of a hat and coat rack, is provided with an opening 13, in which the socket member Patented Aug. 14, 1917. Y

is fitted, the wings or ribs 6 being received in suitable notches or kerfs 14 formed in the member 12, thereby to prevent rotation of the socket member. The head or flange 5 fits snugly against the back of the member 12 or is received in a recess therein so as to hold the socket against endwise movement in one direction. The slotted end of the shank B is then passed through the hub or eye 15 of a hat and coat hook and also through a spacing sleeve 16, and then the slotted end of the Vshank is pushed into the socket A until the kspacing sleeve 16 has been drawn np snugly against Ithe part 12, where it will be eifectually held by reason of the fingers 11 of thedog holding against certain of the ratchet teeth 2. It will, of course, `be understood that the parts 15 and 16 form no part of the present invention, and have been shown in the accompanying drawings merely to illustrate one application of this ting 'within the similarly shaped boreof vthe non-rotatable socket, together with the fact that the opening through the hat and coaty hook is also non-circular, the latter will be held against turning on the shank, thereby overcoming a very objectionable feature in hat and coat hooks as now general-ly secured to hat and'coat rack.

, Should it become necessary or desirable to remove the hat and coat hook, say for instance in shipping the device, a nail or other device may be thrust into the respective openings 3 until theiingers 11 of the dog have been pushed inwardly and out of engagementwith the ratchet teeth, when the shank B may be conveniently withdrawn and the hat and coat hook thereby detached.

In Figs. 6 and7, the present invention has been shown for holding in place an ordinary drawer pully 17, and corresponds in all', detailstowhat has been shown in Figs. 1 to 6, inclusive.

In Fig. 8, there has been shown a swinging @drawer pull 18- consisting of a bail or i handle having its extremities sprunginto eyes 19, each eye being carried by the outer end of the shank B, the remaining portions ofthe fastening being Vthe same as hereini before described.

InFig. 10 of the drawings, 20 designates a bedpost lwhich is provided at its. top 'with a shank'or post B having the slot S, dog 9 `bal pinlO, as hereinbefore described. A orother suitable ornament 21 contains a socket member A, as hereinbefore described, and this socket member is forced down upon the post and the ball orornament held snugly in place in the manner hereinbefore described. If desired, the ball or ornament may be provided with a pair of openings 22 leading to the respective grooves 3 so as to receive nails or other devices for depressing the extremities of the dog to enable the convenient removal of the ball or ornament. The outer ends ofthe openings 22 may be provided with suitable removable closures 23, as desired.

Having thus described the invention, whatV I claim, is
